“The surgery went well,” Dr. Michael Obeng, director of MiKO Plastic Surgery, told CBS Los Angeles. “Tessica is doing well. She’s awake. The hair crew is doing her hair.”

After the four-hour procedure, during which Brown was under light anesthesia, she got choked up when she realized that she could once again run her fingers through her hair, according to TMZ.

In video TMZ shot of the procedure, Obeng explained that he combined medical grade adhesive remover, aloe vera, olive oil and acetone to break down the polyurethane, the main ingredient in Super Glue.
